Is there any difference between medical and cleaning ozone?

What are the main differences between medical ozone (auto-hemotherapy, …) and cleaning ozone (for example, the kitchen cleaning devices for vegetables and food). I noticed that they can produce a lower amount of ozone per hour while the medical ones have bigger amount of production.

“Medical ozone” is a mixture of 0.05 to 5 vol% of ozone produced from medically pure oxygen (usually via silent electrical discharge) and 99.95 to 95 vol% of oxygen. Using air for medical-grade ozone production is strictly forbidden due to formation of hazardous nitrogen oxides $$\ce{NO_x}.$$ Note that ozone therapy is still considered an alternative medicine.
